Root your ICS/JB phone S2 + Samsung + not Samsung phones - No more waiting for custom kernels
This topic provides universal root methods to bypass the use of custom kernels. I took the time to write it as I was tired from waiting for a Dev to publish a custom kernel for the last firmware released.
I will try here to reference most threads and ways to root your phone. Some methods will let you root as soon as you get the new ROM, no more waiting for some dev to release a kernel for you.
I will not list here custom kernels that come with root, you can find them in other threads.
As a general rule, do not forget to take extra precautions when you flash anything: ALWAYS DO A NANDROID BACKUP IN CWM
Method 1 - Recommended
Push superuser + Busybox (Now v1.20.2 from Linus Yang) in recovery
Now, on the i9100 and some other phones (N7000...), you can flash the attached signed zip files in stock recovery, no more need to CWM.
A BIG BIG THANK YOU TO Chainfire for his support that made it possible and to Entropy512 who pushed me to look for a fix
Attached is the CWM Recovery 4.x non touch version, confirmed safe for wiping. It will not superbrick your phone
>>>>>> Now it is even getting greater with attached Clockworkmod v18.104.22.168 !!!! <<<<<<
>>>>>> Also probably safe from brickbug <<<<<<
Special notes about busybox
This method was first inspired from Rachmat3
(do not forget to thank them). I modified it to work in stock recovery, enhanced script, include Chainfire superSU last version + BusyBox last binary. I also keep a ChainsDD superuser version.
- For phones affected by the superbrick bug (i9100, N7000) and that has a stock recovery accepting update.zip files (most phones with a temporary cwm.zip file at Clockworkmod site:
- For most (if not all?) ICS phones having a CWM image at Clockworkmod site:
Fix common issues: You end with both ChainsDD and Chainfire superuser and SuperSU
CF_Root + stock kernel + [optional] Mobile Odin Free version
Here, you use an older CF_Root kernel, and flash your newer stock kernel
Insecure Kernels + SuperOneClick + [optional] Mobile Odin Free
Not tested by me. You get superuser instead of Chainfire superSU + an older busybox
Insecure Kernels + S2 Root - For SAMSUNG Devices
Mobile Odin Free version
Flash your stock kernel from complete ROM file
Now that Intratech stopped releasing stock kernels in his thread
, rooting using methods 2 and 3 can be a problem. In fact, you will not be able to flash your newer original stock kernel after rooting with insecure or cf_root older kernel. You can look in above lyriquidperfection
thread for a stock kernel to flash in odin. But, if you do not like to wait for him to release a kernel, you can get Mobile Odin Free version
Mobile Odin Pro (Payed) version
Root + Flash - You should consider buying it.
With this method, you will have SuperSU from chainfire (that can be updated from market) but no Busybox
You can install busybox from market or from attached CWM_Root_Busybox_1.20.2_Only_(No_SuperSU)-S2-Update2-signed.zip

Chainfire - adbd Insecure app
Getting switchable insecure kernel WITH stock kernel
One of the advantages for some people in CF_Root kernel is the insecure mode. Now, you can have insecure kernel like behavior without flashing a custom kernel. There is a magic app for that, signed Chainfire.
